After posting songs from their catalog online, the band received a cease-and-desist letter from Sony/ATV Music Publishing demanding that they take down their Web site and pay unspecified damages. The band had gained a large Internet following for songs like "I Want to Choke Your Band" and "Leper Madonna."

While Beatallica considers its legal options, its site remains offline. But thousands of fans — including Metallica's drummer Lars Ulrich — are rallying behind the band. Day to Day technology correspondent Xeni Jardin reports.
